I just tried to install the Linux version of Firefox version 23 with vpackager and got the following result:

(Firefox version 23 is in ".bz2" format, by the way). Any suggestions on how to get it installed?

and like I said, is is in "bz2" format (for Linux), which SHOULD make it easy to load via vpackager, but ironically that is where the dilemma is - hence the output that I included in my initial posting.
